Short Answer: arc LM = 110°

Comment

Any two angles that have their end points on the same end points as a chord and both moving away in the same direction (in this case  down ) are equal. This is a fundamental fact about circles.

Equation

2x + 55 =  x + 55

the only way this is going to make any sense is if x = 0. No other value is possible because it will destroy the equality.

Conclusion

Both angles = 55

But that's not what you are asked for.

What you are asked for

You want to know the measure of arc LM.  

The angle connecting the center of the circle with its two arms running through the end points of the chord = the measure of  arc LM

Draw a dot where the center of the circle is and call it O. Draw in <MOL  

<MOL = 2* either of the 55° = 2 (<LKM)  = 2 * 55 = 110° That's a property of the central angle.

The measure of arc LM = 110°

Step-by-step explanation:

the arc lenght is usually described by the following formula:

\(l = \alpha \times r\)

where l is the arc length, alpha the angle(in radians) and r is the radius.

so in this case, using this formula we get

\(l = 75 \times ( \frac{\pi}{180}) \times 5cm\)

we are multiplying 75 x (pi/180) cuz, the angle has to be in radians. then

\(l = \frac{365}{180} \pi \: cm = 6.54 \: cm \: \: aprox\)

more sensible than the last result, considering that the total length of the circle is

L=2(pi)r

in this case L= 31.4 cm aprox

Based on the table, the values relating t and e with their viability is given by:

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

An average rate of change is also referred to as slope and it can be defined as a type of function that describes the average rate at which a quantity changes (decreases or increases) with respect to another quantity, over a period of time.

From the table, we would determine which values are viable points as follows:

At a = -2, we have:

e = 300 - 10t

e = 300 - 10(-2)

e = 300 + 30

e = 330 (not viable).

At b = 3.5, we have:

e = 300 - 10t

e = 300 - 10(3.5)

e = 300 - 35

e = 265 (viable).

At c = 10, we have:

e = 300 - 10t

e = 300 - 10(30)

e = 300 - 300

e = 0 (viable).

Answer:

D. \(10^{\circ}\)

Step-by-step explanation:

Let the measure of minor arc \(AE\) be \(\alpha\) and the measure of minor arc \(BD\) be \(\beta\).

Using the secant-secant theorem, \(\frac{\alpha-\beta}{2}=32 \implies \alpha-\beta=64^{\circ}\).

By the inscribed angle theorem, \(\alpha=84^{\circ}\).

Thus, \(\beta=20^{\circ}\).

By the inscribed angle theorem, \(x=10^{\circ}\).

Answer:

d = 5 is a solution to the equation 13 - d = 8

Step-by-step explanation:

We have to solve 13 - d = 8

Now,

13 - d = 8,

We add d on both sides,

13 - d + d = 8 + d

13 = 8 + d

we subtract 8 from both sides,

13 - 8 = 8 - 8 + d

5 = d

d = 5

Hence the answer is 5

Answer:

10,042.95 squared

Step-by-step explanation:

When finding the area of something, you multiply. And in this case, you are multiplying the base (471.5 ft) by the height (21.3 ft).

A.

Let t be the number of t-shirts you buy and s the number of shorts you buy.

Since each t-shirt you buy cost $4.50 the total cost for t-shirts is:

Since each short you buy cost $6 the total cost for shorts is:

The total cost of your purchase is:

Since you have a total of $108 the equation that models the possible combinations of your purchase is:

B.

If you buy 6 shorts that means that s=6, plugging this value into the equation above and solving for t we have:

Therefore, If you purchased 6 shorts then you can buy 16 t-shirts.

C.

If you buy 10 shirts that means that t=10, plugging this value into the equation in part A and solving for s we have:

Now, since you can't buy half of a short the answer above means ( that:

If you buy 10 shirts then you can buy a maximum of 10 shorts, this wil be a total of $103

Using the substitution the system of equations y + 4 = x and 10x + 2y + 16 is solved to be

Substitution involves replacing a value with it's equal

The given equation include

y + 4 = x

10x + 2y + 16

substituting x = y + 4 into 10x + 2y + 16

10x + 2y + 16

= 10(y + 4) + 2y + 16

= 10y + 40 + 2y + 16

collecting like terms

= 12y + 16

12y = -16

y = -16/12

y = -4/3

substituting y = -4/3 into x = y + 4

x = -4/3 + 4

Answer:

Step-by-step explanation:

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

A coin that independently flips heads with a probability of p. Then, the variance in the number of flips X until the kth head appears is  \(\frac{kq}{p^2}\).

The geometric distribution discusses the number of trials required for each success. Let random variable X be the number of trials needed to get the first success. This variable is a geometric random variable. And the geometric distribution with parameter p is the probability distribution of this variable.

Now, let's consider the number of coin flips to get a head as a geometric random variable (\(X_i\)) with a parameter p. Assuming that X number of coin flips until k heads, \(X=\sum_{i=1}^{k}X_i\). Then, the variance is calculated as,

\(\begin{aligned}\mathrm{Var}[X]&=\mathrm{Var}\left[\sum_{i=1}^{k}X_i\right]\\&=\sum_{i=1}^{k}\mathrm{Var}[X_i]\\&=\sum_{i=1}^{k}\frac{1-p}{p^2}\\&=\frac{k(1-p)}{p^2}\\&=\frac{kq}{p^2}\end{aligned}\)

Since 1-p=q, the required variance is \(\frac{kq}{p^2}\).

95% confidence interval for the ratio of medians is a range of values that we are confident contains the true population ratio, with a specified level of confidence.

A confidence interval is a range of values that we are confident contains the true population parameter, with a specified level of confidence. In this case, we are looking at the ratio of medians in the Verizon data and finding a 95% confidence interval for the ratio.

Let's say the sample median for the first data set is M1 and the sample median for the second data set is M2. The standard error for M1 and M2 can be calculated using the formula for the standard error of the median.

Next, we use the formula for a confidence interval for the ratio of medians:

=> (M1/M2) +/- (Z * SE(M1/M2)),

where Z is the critical value from a standard normal distribution for a 95% confidence level.

The percent bias is the difference between the estimated value and the true value, divided by the true value and expressed as a percentage. In this case, we will calculate the percent bias of the confidence interval for the ratio of medians relative to the standard error.

Finally, we compare the results for the ratio of medians with the results for the ratio of means. This comparison can give us an idea of the difference in the level of accuracy and precision between the two estimates.
